I personel think those metal gasket are all the same size.....They're all the same primary p/n 20692M from 95-03, but they're virtually indestructible as I've said before...I've reused them for 7 yrs thru 3 exhaust system setups......

 

Good to know. Brian says he included all new gaskets except for the one at the end of the cat to the beginning of the b pipe. I guess he was figuring on people re-using the metal gasket as well. You guys that have replaced your own exhaust have any problems backing out the O2 sensors? This will be my first time replacing an exhaust on my own.. any tips to make the job easier are welcome.

 

Spray the threads with PB Blaster a few times, waiting several minutes between applications. When you put it back in, pre-wind the O2 sensor in the counterclockwise direction so that when it's fully tightened, the wiring looks good and not all bunched/tangled up from being twisted.. Also, add just a touch of anti-seize as well.

 

Damn that looks good!!

 

Did this, and no luck on mine, I ended up buying a new sensor because we stripped the screw.

But I only did 2 applications of PB blaster + fiyah, so to others who may install this, get a can of it and go crazy, let that thing soak it in really really good... Unless you just wanna spend $60.

And please buy an 02 sensor socket if you don't already have one, it's only $5

BTW, I dont know if this is true for all 02 sensors but Bosch includes anti-sieze on their threads already if purchased new, but of course if you are re-using your old one you would want to add a drop or two of Anti-Seize like the wiz said.

 

Damn stock looks horrible side by side with that Cattman!!

 

Ive never used an O2 socket, on any of my vehicles. I do use the PB Blaster though. I use that stuff on just about everything under the car, especially exhaust components.

 

Thanks for all the tips fellas. What is PB blaster? Some type of lubricant or something? Anything equivalent to that incase I can't find it?

As for jacking up the car.. Is just setting the rear on jack stands sufficient enough to replace the exhaust? Or do I need to have the whole car on 4 jack stands?

 

Its a penetrating catalyst. There are a few others out there tha tdo the same thing, but PB Blaster works really well.

 

I got it.. Found it at Grainger. Its also a rust inhibitor.

 

I did mine with two jack stands.

 

I'm very glad that you guys seem pleased with the results - looks like this product is a success.

We've got FOUR more sets in stock that are still available at the introductory price of $725, so please spread the word.

Brian

 

Cool, thanks Smelly. Once I get a chance to install mine I'll post back with my thoughts compared to the 2.5 Cattman exhaust.

 

It's a mechanic's personal lubrication.......!!!!!!!LOL

 

WTF... no one has these dam exhaust hangers locally, is everyone installing dam exhaust these days?!. I found the walker 35725 for 15 bucks each on some summit website... kind of expensive for a dam piece of rubber.

 

I ordered some Knees-mos hangars last Friday.

 

$15 a pop.... really not any better than those less expensive Walkers. I bought some of both brands!

 

Apparently they're pretty much the same price...

 

How do you figure? Nismo-$15/ea.....Walker-$5/ea.......

 

Going by what Maxprivate said a few posts up...hence the quote.

 

I found the Walkers for 15 a piece on some website. If you search around more then you can find them for 5 or 6 bucks . I couldn't find the 35460 ones though.

Wiz, care to post where you found the Nismo ones? Part numbers?

 

nismo part number: 20651-RS230

http://www.g35parts.com/NISMO-Exhaus...0651-rs230.htm

 

Looks like 99greddy answered you already, but there's always good ol' Courtesy Nissan besides g35parts.

http://www.courtesyparts.com/nismo-e...ath=2837_5874&

These are the only two places I could find easily.

 

Courtesy has them on back order. No time line on when they will receive more.

 

True. When I spoke to Steve at Courtesy last week, he said he'd have more in by next Wed the 16th.

 

Website doesn't work, just called courtesy.. this guy named Dave told me they been on back order for quite a while with no estimate as to when they will come in. geez... I thought these would be readily available.

 

I REALLY need one of these. The current 3" no resonator/Dynomax Super Turbo muffler combo is killing me.

 

Website works now. Do I need to order 4 of the Nismo 20651? The reason I ask is because Brian listed two different part numbers for the walkers exhaust hangers. He said to purchase 3 of the one part number and 1 of the other. For Nismo, its only one part number.. so I just want to make sure Im getting the right ones.

 

No, you order 3 of the Nismo ones if you wish. All three go where the muffler is. Nismo doesn't make an equivalent for the one upstream, although it just might work. (I'm under the car right now and it's the distance between the holes is only slightly more)

I'm going to try my luck with just the 3 Nismos at the muffler for now. If it still bangs, I'll track down the other one and order two of them (double up). I'll explain more shortly.

BTW, the Nismo hangers arrived today. Nothing exciting, but pics to follow.

 

Here's the NAPA stuff......

Wiz, no need to double up on the one down stream. You can use the hose clamp method Brian suggested. This will limit the movement of the exhaust hanger.

 

Give us a call, usually we can ship it out the same day if the order's received before 3pm (2pm your time). 800.759.9920, open 9-5 MST, M-F. I'm sure you'll be much more satisfied with this system.

Brian

 

Hey fellas, I checked with a local Napa and they can order the Walker ones and have them for me today! they are only 4.95 each, so I'll just use those with the hose clamp like Brian mentioned. He told me the 5th gen guys are using the same method and that its working out well for them. Hopefully this weekend I can get mine installed.

 

Maxprivate and I were just chatting on the phone and he mentioned there's a lot of discussion about expensive hangers. The NISMO hangers are very robust, but very expensive, though I think they're easier to get now than they were a few years ago when they were very "grey market".

Let me "re-add" my $.02 to this. Try out the standard, run-of-the-mill rubber hangers with a small hose clamp around the outside. Tighten up the clamps to limit movement, but not enough to crush or deform the hanger. It works great, and you can adjust the clamps to hold the system as tight as necessary, move and hold the b-pipe slightly to either side, up or down, etc. to prevent rattling under stress or fine-tune the position of the tip in the valance cutout. Even the $15 hangers don't provide adjustability.

Brian

 

If you're going to hose clamp it, do you even need new hangers? Waste of money perhaps?

And here's my 2.5" Cattman system on my 99 Max. I can't remember if I did this on my own, or Brian told me to.

 

I think that even with clamps, fresh rubber is a good idea (actually I think fresh rubbers are always a good idea, hate those used ones ). Not sure if they have to be the $15 variety, but start out with new.

 

Brian, sent you a PM

 

Attempted to install the exhaust on my own yesterday and what a pain the ****! All the bolts are rusted to ****! even letting the PB blaster soak for hours didn't help much. After using some WD 40 and a large pipe wrench was able to free the bolt on the muffler flange. That took almost 40 min for one bolt.

I realizes between school, exams this weekend, and work I just don't have the time to do this. Im just going to suck it up and pay to have it installed.

For you guys that have installed your 3" Cattman.. Did you guys buy the larger 2001 2001 maxima gasket for in between the cat and beginning of B pipe? It supposed to have a bigger hole to match the now larger exhaust opening.

 

I need 3" my Cattman 2.5" is too quiet, even with headers and test pipe.

 

Ordered mine today. We'll see how well this 3.5 breathes after the install. I'll try and get a good sound clip afterwards. Mods are in my sig...
